(Cl. 18S-51) 1 claim. 1

This invention relates to a dust collecting bag and filter for vacuum cleaners.

Vacuum cleaners of the type shown and described in Patent No. 2,198,568, issued to Edward H. Yonkers, Jr. on April 23, 1940, =are generally provided with a cellulose filter and a metal dust collecting pan or container. The pan or container must be emptied from time to time in order to dispose of the collected dust. This is a messy process which housewives invariably detest.

It is the principal o'bject of this invention to provide a combination dust collecting bag and filter which may beused in connection with the aforementioned type of vacuum cleaner. It comprises a paper bag or a bag made of other disposable material, which may be introduced into the dust collecting pan or container. A cellulose filter or a filter made of other suitable material is either permanently-or detachably fastened to the bag and it occupies the same general position in the pan or container which the cellulose filter in the Yonkers patent is shown to occupy. An opening is provided in the side of the bag to register with a corresponding opening in the side wall of the dust collecting pan or container to provide communication between the suction hose and the inside of said bag. The air impeller is mounted on the opposite side of the lter from the bag. 'I'hus the Vacuum cleaner under discussion performs in precisely the same manner as the vacuum cleaner in the Yonkers patent performs, with the sole exception that the dust is collected in a bag instead of in the pan or container itself. The problem of disposing of the collected dust is accordingly greatly simplified. The dust may be disposed of by simply disposing of the bag which contains it.

The invention may assume two important forms: in the one form the filter and 'bag are permanently attached to each other, and in the rsecond form, they are supported separately and are held-together only temporarily between the top of the dust collecting pan or container and the peripheral iiange on the cone-shaped perforated plate against which the filter rests. No change is contemplated or required in the construction of the vacuum cleaner itself.

It appears necessary to anchor the bottom wall of the dust collecting bag to the floor of the dust collecting pan or container. This may be achieved in many ways and by various means. Preferred methods and means are shown in the accompanying drawing. In one case, a cellulose adhesive is used to detachably secure the bottom wall of the bag to the floor of the pan or conl tainer. In another case, the dust collecting bag is provided with-a bead or ilange along its peripheral bottom edge and a sleeve or ring or other suitable retaining member is provided to engage said bead or flange and hold it down upon the floor of the pan or container. In both cases the bag may readily be removed from the pan or container for dust disposing purposes.

Preferred forms of this invention are shown the accompanying drawing in which:

Fig. 1 is a side view of a vacuum cleaner inv which a dust collecting bag and lter are installed. the housing and pan of said vacuum cleaner be- Fig. 3 is another view, somewhat similar to that` of Fig. l, showing another form of dust collecting bag and lter, wherein the bag and the filter are permanently fastened to each other.

Referring now to Fig. 2, it will be seen that the first form of dust collecting bag and filter III comprises the following elements: a bag I I, a filter I2, an adhesive member I3, and a tubular intake member I4. Bag II is shaped for insertion into the pan or container I5 of vacuum cleaner I6. Since the container is generally cylindrical in shape, so is the bag. The respective dimensions of said bag and lsaid container are such that the bottom wall I'I rests snugly upon iioor I8 of the container and cylindrical wall I9 of the bag rests snugly against the inside surface of cylindrical flange 2| is adapted to rest upon annular shoulder 2?. of said container. Tubular intake member I4 of the bag is adapted to register with tubular inlet member 23 of the container,` and to project therethrough. It will be noted that an opening 24 is formed in the bottom wall I'I of the bag and it will be further ,noted that adhesive member I3 extends across said opening. More specifically, the adhesive member is afhxed to the inside of the bag, its adhesive side or surface facing downwardly. Thus by pressing upon the top of said adhesive member, it may be caused to project through said opening 24 and to secure itselfv to the oor of the container. See Fig. l.

Filter I2 is cone-shaped. The angle which it describes corresponds to the angle of the coneshaped perforated plate 25 of the vacuum cleaner. Like said cone-shaped plate 25 which has an annular ange 26 formed -peripherally thereof and extending radially outwardly therefrom, Ifilter I2 has an annular ange 2l which is also formed peripherally thereof and extending radially outwardly therefrom. Flange ZI of the bag, flange 21 of the lter, and flange 26 of the perforated plate -all correspond to each other and they are al1 adapted to be supported `'by the annular shoulder 22 of the pan or container. They mayl be supported directly upon saidv
